These tables have only the most typical host crystals; a lot of Some others exist, which happen to be significantly less often utilized.
激光晶体的极化性能可能会影响输出激光束的质量和特性。有些激光晶体产生线性偏振光，这对某些应用可能有益。
为了使激光器有效运作，需要有效管理运行过程中产生的热量。具有良好热导率的激光晶体可以更有效地散热，防止热透镜效应或断裂。
激光晶体中活性离子的作用是什么？ 活性离子在激光晶体中负责通过受激发射产生激光光线。
Which geometry, dopant and doping focus on the attain medium are most advantageous depend on many factors. The offered pump resource (variety of laser diode or lamp) as well as the envisaged pumping arrangement are crucial aspects, but the fabric alone also has some impact. For instance, titanium–sapphire lasers need to be pumped with significant intensities, for which the form of a transversely cooled rod, operated with rather little pump and laser beam diameter, is more correct than e.
激光晶体由发光中心和基质晶体两部分组成。大部分激光晶体的发光中心由激活离子构成，激活离子部分取代基质晶体中的阳离子形成掺杂型激光晶体。激活离子成为基质晶体组分的一部分时，则构成自激活激光晶体。
Obviously, it's very desirable that a specified crystal good quality is produced persistently, although distinct laser layouts can have a distinct sensitivity to product parameters.
The most possible doping concentration can rely strongly to the host material and its fabrication method.
Laser modeling and simulation can be employed to reliably establish the optimum crystal Proportions, doping density and possibly values of supplemental parameters.
量子效率是发射光子数量与吸收光子数量的比率。高量子效率表明更大部分吸收能量被转化为激光光束，有助于提高激光的整体效率。
It is clear that diverse programs bring about extremely diverse prerequisites on laser obtain media. Due to this, a wide assortment of different crystals are made use of, and building get more info the proper preference is important for constructing lasers with the best possible functionality.

In 2017, we produced the entire world’s premier Ti∶sapphire crystal (Φ235 mm), which supported The ten PW laser output of Shanghai Superintense Ultrafast Laser Facility. The event of Yb and Tm doped GdScO3 laser crystals with incredibly extensive emission spectra drives the development of laser diode pumped ultrafast solid-point out lasers. With the rise in pulse Vitality, peak energy, and repetition rate of good-point out lasers, laser crystals will produce towards larger dimensions, increased crystal top quality, and controllable important performance.
Applying our promoting offer, you'll be able to Display screen your emblem, further beneath your solution description, and these will been found by a lot of photonics professionals.
激光晶体（laser crystal），可将外界提供的能量通过光学谐振腔转化为在空间和时间上相干的具有高度平行性和单色性激光的晶体材料。是晶体激光器的工作物质。
